BOTTLE-FILLING Mam-uni.

SPECIFICATION forming art of Letters Patent no. 619,474, dated February 14,1899.

. Application filed January 27, 1898. :erial'N0- 668,108. (No model.)

To (1.7] whom it may concern:

Be it known that LVVILLIAM MI ES Fow LER, a citizen of the United States, and a resi dent of Stamford, in the county of Fairfieldand State of Connecticut, have invented a new and useful Improvementin Bottle-Filling My invention further, contemplates means.

for returning any foam, gas, or liquid-which may escape from the distributing reservoir or bottles orother vessels to the supply-vessel while maintaining the aforesaid pressures and for effectually shutting ofi drip from the filler when the latter is removed from the bottle or other vessel.

A practical embodiment of my invention is represented in,the accompanying drawings, in which- 5 Figure l is a view of the machine in end elevation,'partly in section. Fig. 2 is a rear elevation; and Figs. 3, 4, and 5 represent elongated views in detail, showing the filler in longitudinal section and the parts in the po- SiliOnS which they assume when the sealinghead on the filler first engages the. mouth of the bottle, when the filler has been still further depressed, and in the depressed position for filling.

The frame conveniently consists of a bedpiece A, supported by sets of legs a a and surmounted by a pair of standards B B, between which the distributing-reservoir O is mounted to slide down and up'to introduce the fillers D into and withdraw them from the bottles E or other vessels to be filled. The reservoir 0 and the fillers D carried thereby are lowered by an operating-treadle F, connected with the slides c at the opposite ends of the reservoir by rods 'fand are returned by the retracting-spring f.

The supply-cask is denoted by G and is connected, with the distributing-reservoir by a pipe g, leading from a point at or .near the bottom of the cask to the distributing-reservoir.

The upper portion of the cask G is connected by a pipe h with the upper end of a umpcylinder H, the lower end of the cyl-in er-being connected with the bottom ofan expansion-chamber I by a pipe h.

The upper portion of the expansion-chambe! I is connected by a pipe i and branch pipe 1) with the'top of the distributing-reservoir C and with the several nipples d, connected with the tubular casings d of the fillersl);

The casing d has fixed to its lower end the sealing-head d for engaging the mouth of the 1 bottle E, as clearly shown in Figs. 3, 4, and

5, and is fitted-at its upper end to slide within' a'tu'bular casing K, the two casings d and K being held normally eitended by means of a spring L, interposed between should ers d and lo.

. The filling-tube (Z is fitted to slide within the casing dand has fi'xed thereto a valve d which when the tube 01 is in its raised position (shown in Fig. 3) outs olf communication between that part of the interior of the casing d which is open to the interior of the vessel being filled and the nipple d. The valve d also limits the movement of the filling-tube d relatively to the casing d by its engagement with thevalve-seat at one end of its-movement and with the top .of the seal head at the opposite end of its movement. The tube d is promptly thrown to the limit of its downward movement when released by a spring I, interposed between the valve (1 and an interior shoulder on the casing d.

The valve for opening and closing the lower end of the filler-tube d is denoted by M, its stem m extending upwardly through the interior of the tube (1* to its point of attach-' ment at m to a yoke on the casing K.

The structure of the filler is such that when the sealing-head d is lowered into engagement with the bottle and the downward movenn'ent of the distrib'uting-reservoir is continued the compression of the spring L by the movement of the casing K relatively to the casing d, while the latter is held by the b0);- tle against movement, will at first permit the spring Z, assisted by gravity, to slide the tube (1 within the casing 01, as shown in Fig, t, until the valve 01 strikes the abutment at the top of the sealing-head, thereby opening the interior of the ,bottle to the nipple d and rco through it to the pipe z" and 11, leading tothej expansion-chamber I. The further downward movement. of the distributing-reservoir and easing K, attached thereto, will open the val v6 M from the end of the tube 61, as shown in Fig. 5, and permit the liquid from the dis= tributing-reservoir to enter the bottle, while the escaping air, gas, and foam, if there be any, will pass to the expansion-chamber I.

- The upward movement of the" distributingreservoir will first close the end of the fillingtube by the return of the valve M to its seat and finally lift the valve M and the tube (1 bodily into the position shown in Fig. 3, with the valve (1 seated, thereby cutting off any possible drip from the nipple and pipes in communication therewith.

The piston of the pump, the cylinder of which is denoted by H, is actuated by a rod h ,-connected with the arm not an operating lever N. The bottles or other vessels to be filled may be fed'step by stepin any wellknown or approved manner.

When thepump-piston is lifted, it will permit the air, gas, and any liquid which mayhave accumulated in the expansion-chamber 11 to rush into the cylinder H, at the sametime forcing the air, gas, and liquid above the. pis ton into-the top of the supply-cask through ,7

the pipe h. As the piston of the pump-descends the air, gas, and liquid beneath it pass through a valve (not shown) of any-wellknown or approved form in the piston to the. upper side of the piston, to be forced into the cask at the next stroke of the piston. The pressure within the cask is thus maintained and at the same time a "corresponding pressu-re is at all times exerted on the liquid within the bottle and distributing-reservoir,

since the pump-cylinder on both sides of the pump-piston is at all tiinesin communication either. directly or indirectly with the interior of the supply-tasln' This .constant pressureexertedon the liquid serves to prevent it, as in the case of bottling-beer, from foaming'to any great extent, and hence serves to. keep it from deterioration during the-bottling opera tion. i

- It is obvious that changes might be resorted to in the form and arrangementof the parts. 1

without departing from the spirit and scope of my invention, Hence I do not wish tot limit myself to the structure and described; but i What I claim is- 1. A bottling-machine comprising a supply cask or vessel, a distributing-reservoir incomherein shown j ary, 18.98.

munication therewith,-a filler. in communication. with the distributing-reservoir, a pump, a conduit connecting one end of the pumpcylinder with the supply cask or vessel, a conduit connecting the opposite end of the pumpcylinder with the filler and with the distributing-reservpir and means for operating the filler, substantially as set forth.

2. A bottling-machine comprising a supply I cask or vessel, a distributing-reservoir in connection therewith, a pump, a conduit connecting one end of the pump-cylinder with the supply cask or vessel, an expansion-chamber, a pipe connecting the opposite end of the ,pump with the expansion-chamber, a filler connected with the'distribu ting-reservoir and conduits connecting the filler and distribut ing-reservoir with the expansion-chamber, substantially as set forth.

3. .A filler coin prisinga filling-tube, tubular casings movable relatively to each other and to the'fillingtube, an overflow-conduit connected with one of the casings, a valve carried by the filling-tube for opening and clos: in g communication between the overflow-conduit and interior of the vessel being filled, a valve under. the control of another casing for opening and closing the, filling-tube and a spring interposed between the casings, substantially as set forth. I

4. The combination with the tubular casings movable relatively to one another and the spring interposed ,between the casings, of afilling-tube movable relatively to the said tubular casings and a valve carried by one of the casings for opening and closing the fillingtube and for bodily moving the filling-tube relatively to the casings, substantially as set forth.

5. The combination with the tubular casings movable relatively to one another. and a spring interposed between the casings, of a filling-tube movable with respect to the tubular casings, a spring under tension tending-to throwthe filling-tube in one direction and a valve carried by one of the tubular sections and engaged with the filling-tube and tending Y to hold the filling-tube. against the tension of the aforesaid spring,substantially asset forth;

In testimony that I claim the foregoing as my invention I have signed my name, in pres ence of two witnesses, this 26th day of J anu- WILLIAM MILES FOWLER.
